Application filed June 10 1919. Serial No. 303,169.

To all whom it may concern:

Be it known that I, WILLBURN C. GRANT, a citizen of the United States,residing at Abilene, in the county of Taylor and State of Texas, haveinvented a new and useful Ice- Machine, of which the following is aspecification.

This invention relates to machines for manufacturing ice.

One of the objects of the invention is to combine with the refrigeratinga paratus a means whereby the water used or coolin; the jackets of thecompressor is also used to spray over the ammonia condensing coil of t eapparatus after which the water is collected and again directed into thejacket of the compressor.

A further ob'ect is to provide means whereby a force circulation of thewater is set u the pum used for this purpose operate with anot er pumpemployed for producing a circulation of the brine in the freezin tank.

ith the foregoing and other objects in view, which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that, within the scope ofwhat is claimed, changes in the precise embodiment of the inventionshown can be made without departing from the spirit of the invention.

In the accompanying drawing, which is a diagrammatic view partly in planand partly in elevation of the apparatus constituting the presentinvention, the preferred form of the invention has been shown. The tank,on 'ne and compressor are shown in lan while the condensing coils andwater collecting tank 31 are shown in elevation.

Referring to the drawings by characters of reference 1 designates abrine tank in which are arranged cans 2 havin central An ammonia coi 4is arranged within the tank and around the cans and then communicatesthrough a pipe 5 with an ammonia tank 6. The other-end o the coil 4 isconnected by a pipe 7 with the inlet port of a compressor 8. An ammoniacondensing coil 9 is connected at its lower end by a pipe 10 to theammonia tank 6 while its other end is connected by a pipe 11 to thecompressor 8.

Arranged adjacent the brine tank is a pump cylinder 12 in which islocated a pisto1r13 connected to a rod 14 which extends entirely throughthe cylinder and is suitably guided, a pitman 15 connects the rod to aneccentric 16 so that during the rotation of the shaft 17 the said pistonwil l be reciprocated. Said shaft 17 is adapted to be driven by anysuitable mechanism such as a belt mounted on a pulley 18 and a pitman 19may be employed for transmitting motion from a crank 20 to thecompressor 8 as will be obvious.

A pipe 21 extends from the cylinder 12 and into the brine tank 1 and areturn ipe 22 is arranged in the bottom portion of the brine tank andhas branch pipes 23 provided with upwardly extending nozzles 24 locatedin the cores 3. Valves may be suitably arranged so that, when the piston13 is reciprocated, circulation of brine will be set up in the tank,some of the brine being sucked through the nozzles 24 and the pipes 23to. the pipe 22 and thence to pipe 21 min which it will be dischargedback into the tank, thus completing the circulation of brine.

Another pump cylinder 25 is arranged in line with the cylinder 12 andhas a piston 26 therein connected to and movable with the rod 14. Anoutlet pipe 27 extends from the cylinder 25 to a s ra pipe 28 arranabove the coil 9 an this outlet pipe may be provided with a check valve29 to prevent return flow of water within the pipe. A pan 30 is arrangedunder the coil for collecting the water after it has gravitated over thecoil 9 and this pan opens downwardly into a tank 31 from which a pipe 32extends to the water jacket of the condenser 8. Another pipe 33 extendsfrom said water 'acket to the cylinder 25 and may be rovide with a checkvalve 34 to prevent ow of water from the cylinder 25 back to the waterjacket.

From the foregoing it will be apparent that during the o eration of thecompressor the piston 26 wil be reciprocated and will set up acirculation of water, said water being sucked out of the water jacket ofthe compressor 8 and forced through the pipe 27 to the s ray pipe 28.From this dpipe t he water wil fall onto the coil 9 an trickle down tothe pan 30. From this pan it will enter the tank 31 and will return, byway of ged86 the pipe 32, to the water jacket 8. Thus the same waterused for spraying the coil 9 is used for cooling the compressor.

What is claimed is:

In an apparatus of the class described the combination with an ammoniacondensing coil, and a compressor provided with a water jacket, of awater tank in communication with said jacket, a pan for collecting waterfrom under the ammonia condensing coil and directing it to the tank, apump, a.

'pipe connection between the water jacket and the pump, a spray pipeextending over the ammonia condensing coil and a pipe connection betweensaid s ray pipe and pump. In testimony that I c aim the foregoing as myown, I have hereto affixed my signature in the presence of twowitnesses.
